WhatsApp is making its Chat Lock tool even more secure by introducing Secret Codes that will hide private chat rooms.
The way it currently works, Chat Lock takes conversations and places them into a separate folder that can only be opened with either your phone’s password or biometric login. This can be helpful if you share the device with others. However, it doesn’t stop other people who know the password from taking a peek at any time. Secret Codes addresses this by allowing users to implement a second password separate “from what you use to unlock your phone”. Creating one, according to WhatsApp’s announcement, will cause your locked folder to disappear from your inbox as an extra layer of privacy.
